How about this:
def recursiveDictFactory():
return defaultdict(recursiveDictFactory)
dictOfDictsOfDictsEtc = defaultdict(recursiveDictFactory)

Also you are overwriting the row for each name. So you only
store the last entry. So you need to separate the data further.
Something like
maindict[row[name]] [row[day]] = (row.weight, row,temp)
This will not quite work. It will give KeyErrors because the
second-level dicts don't exist in maindict. One way to fix this is to
use collections.defaultdict:
from collections import defaultdict
maindict = defaultdict(dict)
Now maindict uses an empty dictionary as its default value.
For another level of nesting (the 'Day' level you show in your
example) this becomes a bit more complex, see this discussion and the
